| 英文摘要 | A series of sba-15-supported wo3 catalysts was prepared by impregnating silicotungstic acid on sba-15 (hsiw-sba-15) and subsequently calcining at different temperatures. it shows higher catalytic activity and stability than the physical mixtures of sba-15 and wo3 in the self-metathesis of 1-butene to propene. the calcination temperature of hsiw-sba-15 has a significant effect on its catalytic performance. the sample calcined at 700 degrees c gave a 1-butene conversion and a propene selectivity of 59.6% and 59.7%, respectively, at 350 degrees c. it was found that the metathesis of 1-butene to propene occurred via two steps. the first one was isomerization of 1-butene to 2-butene on both bronsted and lewis acid sites, and the second one was metathesis of 1-butene and 2-butene to propene via the formation of w-carbene species (w=chch3, w=ch2 and w=chch2ch3). the si-o-w-oh bronsted acid sites play a decisive role in the formation of w-carbene species, and the pseudo-wittig mechanism dominates the process. |
